A seat supporting post Ill is provided and is enclosed at its lower end in a ringed socket or cage II, the same comprising a pair of spaced collars or rings Ha, lib, connected by a neck piece No, as shown in Figure 2 of the drawing. The ring or collar No is pinned to the post ID as indicated at 1 Id (Figures5 and 6} Thispo st and its encirclinglower'rin'gH la isibored'through as at l2, as means for jourhaling the post upon the outer end of the reach-rod 8. Before this is done however, a stop-bracket l3 (Figure 5), formed with an arcuate ninety degr'eiwldtfi I311 at' its'r outer lateral margin, and with a concentric, l5

bored hub l3b at its inner corner, is "keyeofupon- J the outer end of the reach rod 8 in a spaced're lation from the extremity thereof;-by:insertingg the end of the rod through the hub l3b and then passing a pin [4 through the hub and rod: The post In is then journaled upon the extended end oftheTeach-rod' 8 outward-lyof the stop bracket l3 and' 'is operatively secured-in place=by borin and ta'.'pping the endof "the rod and seating headed" set screw 14a into this 1 threaded' bore; The post I!) is additionallybored through a"s'*=at lizin spaced and parallel relation to the bore l2'} and in exactalignment {with the arc'uateslot l 3d of "theib racket 3. A headed 1100a pin" 1 a; is t en assed through 'the slottatt amig't r tigh the-bore so l5 or the post In, the outer end of thef -lock-pin being threaded to engage *a lock-nut" l 6a."

by turning up the nut lBa, the bracket'l 3' is drawn ufi'against the neck piece I lc oi' the socket" for"frictionally locking thepost" lll' to anyad: 36 justed position, such as to the vertical positionas required in the use of this toilet seat assembly.

A ca 11 is" pinned as at Ha ato'p}' the post 'l u; and bearing lugs l8 are rigidlyeiztend'ed, in alignment, from the capl'l ar'id 'fi'orn'}the or" collar l lb of the" socket' ll. These bearing lugs are formed with sockets [But for receivin the reduced and" journaled ends l9a of a wor I9 (Figure 6). A drivenpinion-bevel gear fll*is keyed, as at20a, Figure 3, upon the-"lower end off theworm' l9, above thelower bearing lug 18?; An integrally formed collar -brack'et-oryoke 2| is; provided, andismountedby passing the post lB through the collar 2| a thereofiiFigure 6) and keying it'irfplaceas at 21b; The bracket-pot: so tion.2 lc of thisyoke isopen, as at '2 d, and in the assembling of the elements; the w tm l9 is passed through this open portion of'the yokei 'fheouter end of the bracket portion-2 lc stored through, as at Zle, and a stub drive shaft? 2 2515 65 journaled through"this*bore.'

A handle'ZAb-is extended irom'; the'wheel 24. Aftoilet seat supporting collar or" seat elevator collar- 25 is "slidablymou'nt'ed upon the post [0, and a'lug 25a is rigidly anchored to th'i'sfcollar, as shown at'25 b, thislug beingbored and tapped as at 25c"for threa'dedly engaging the j worm l9," this arrangement be ingj thus-elfectuated in assemblingthese elements of theunit.

A'sh and Sturdy seat supportingb a'r' 0Y (Figures 2, 3," 1) is rigidly'joined to' and-e X- tended horizontally from the inner side of the elevator collar 25; in position to extend inwardly' over the bed in the use andoperation of the unit'.

As here shown, however, a flat, U- shaped, metallic seat-plate 21a (Figure 2) is welded or otherwise anchored to the inner end of the arm 26 and thus arranged for horizontal extension inwardly over the bed when in use. Metallic guide strips 21?) are anchored atop the legs of the seat-plate in parallel relation, and these guide-strips are extended rearwardly, as shown at 21c, and are notchedat their upper sides;v as atgfld (Figure AT-.1 The stripsg' flb are marginally undercut, as"'at"21 (Figure 2), and thus adapted to slidably and lockingly engage 'aU-shaped Wooden seat 21f which is formed at its-rundeflside; with marginally undercut guidegrooves 21g for receiving and holding the complementally formed guide-strips 21b.
